Sarah was asked to round 4 7/8 in to the nearest 1/2 inch and to the nearest inch. Her answer was the same. Explain why Sarah is correct.

Would it be 5 inches. :)

Hello skateboarder

Oh glorious decimal system, where this is much easier to see !

half inch = 4/8 inch
hole inch = 7/7 (0/8) and 8/8 inch

half spacing between half inches is 2/8 and 6/8
half spacing between full inches is 4/8

4 7/8 --> nearest half inch = 4 + 8/8 = 5

4 7/8 --> nearest inch = 4 + 8/8 = 5
